Be' it h'noivn that it, CHARLES H. GENTEL, a citif'zen ot the UnitedStates, nesiding at Brooklyn, in .the county of Kings, State of NewYork, have invented certain new and 'useful Iiiipro-vements inCoconut-Shredding Machines; and I do `hereby declare `the following tobe a full, clear, and exact description of the invention, such willenable others skilled in the art to which it appertains to make and usethe same. Y y

rihis invention relates to machines for extracting meat 'from coconuts,and delivering it in the torm ot shreds .ot a sinieand shape suitablefor commercial distribution. In such machines a part 10i a coconuthaving an open end is held by suitable Agripping devices, and the meatwithin `the shell subjected to the action et the shreddingftool. For4this purpose the inut and the tool are given a relative movement otrotation anda relative movement oi translation, and the two movementsare so coordinated that the cutting end of the tool, following a spiralpath with relation to the nutshell, gradually attacks all portions ofthe meat contained therein and delivers the meat in the `torni otshreds. These machines as used heretofore, require that the operatorshall insert each new nut in place in the holder, move the tool toproper Vposition so v,that it can :act on the nut, and then connect thepower driven devices with thesource ot power, zas, 4tor instance, `bymeans of a clutch. During the shredding opera-tion, theoperator mustgive his attention to the machine so 4that heA may stop the machine whenall'the `meat :has been removed from the shell. The ycontrol or" `themachine is, heret'ore, Wholly manual, and the operator must have aconsiderable de-y gree of skill in order that the machine may produce'the maximum output.

The machine of the present invention is designed to avoid thesedisadvantages and it includes appropriate mechanism for bringing theextracting operation to a -stop at any predeterminedpoint, preferablywhen the entire contents ot the `shell have been removed. For thispurpose, Athe machine includes a holder ter a portion of a nut, a toolby Whichythe meat is extracted, power driven devices by which the n utholder and thetool may be given a relative movement 1924. Serial No.725,178.

of rotation and a relative movement of translation, and mechanism forstopping the relative movement of translation at any selected point. 'Tothis Iend the .curvature of the inner wall of the shell is ,takenadvantage of, and in `this machine fthe first rela.- tive movementcarried `on rpreferably by rotating the nut holder while the `tool11emains in a relatively fixed position, and the second movement bycausing the tool to advance in to the open end Aot the nut held in thennt holder. The tool is held in a device which permits it to bearagainst the inner Wall ot the lshell With a yielding pressure, and as,it moves into the rnut `While the latter is rotating, the xcuttingknives attack the meat along a spiral path. The portion of the`n-utwhich 'is acted on is preferably halt1 a coconut', produced ,by atransverse cut, and

as the 4tool follows its curved inner `ivall, it

Savings about an axis.. The mechanism by which the relative movementottranslation ofthe `nut 7and `|the tool is produced includes a clutchof Yappropriate form and when the tool has been lswung in the manner.described, `to ya selected position, it actuates a latch deviceassociated with the clutch mechanism so -as to ithrow `out the clutch.Vith such :an arrangement the amount `of skill required `on fthe part ottheoperator Aisa mini.-

mum, and no injury can result to the ina-- chine from a lack et:attention on his part. 'Dhe machine also incliides a suitable device bywhich a halt nut lmay be quickly inserted in athe 'gripping devices, andalso convenient means tor delivering the extracted meat. The severalpower dri-ven ,devices are `so `designed that the operation totinserting and centering the nugt in yits holder, and-of bringing the-tool into operative relation thereto may be carried on rapidly andyWithout expert manipulation. The invention, theretore, provides amachine in lwhich theeX- tracting ot the meat from the `shell may becarried -on practically automatically, and

`xvhile this extracting operation isi taking place the operator puts anew portion 'of a nut inthe Iinserting device so .that when the contentshave `been removed from one nutshell 4a new gone may be Iplaced .in the@machine and the l,machine started with but small delay. i

`Fig. 10 is an enlarged detail of a clutching device associated with thenut holding mechanism.

Referring now to these drawings, the machine is shown as mounted on abed plate 11, part of the mechanism being mounted on a table 12,supported above the bed plate at any convenient height on legs 13.Mounted in suitable bearings in the table 12 and inthe supportingmembers therefor, is a vertical shaft 14 which carries a bevel gear 15beneath the table. Eneircling the shaft below the bevel gear is a. plate16 having a hub 17 through which the shaft extends, and mounted on thisplate is a bearing 13 for a horizontal shaft 19, this shaft carrying abevel gear 20 meshing with the gear 15. lVith this arrangement the shaft19 is driven fromthe shaft 14 and the shaft 19 is capable of being swungabout the shaft 14 while retaining the driving connection therewith. Atits upper end above the table 12, the shaft 14 carries a bevel gear 21,which, in turn,

meshes with a bevel gear 22 on a shaft 23, one end of which is journaledin a bracket .24 of suitable form bolted to the top of the "able, theother end being supported in a similar bearing 25, provided with a cap26 bolted thereto and holding the shaft 23 tirmly in position. e

At one end the shaft carries a chuck which is composed of a casting 27secured to the shaft and rotatable therewith, and a ring 28 enclosing aportion of the circumference of the casting and having a flanged end 29eX- tending therebeyond. Projecting beyond the outer face of the casting27 is a circular flange 30 having slots 31 formed in it' in spacedrelation. These-slots are illustrated in Fig. 4 as being three innumber, and lying within each slot is a bell crank lever 32, pivoted inposition at 33. The shorter upper arm of the bell crank carries a ball34 which is gripped within a socket formed partly in the end of theflange 29 and partly in a plate 35 bolted to the face of this flange andserving to hold the ball firmly in position within its socket. At theouter end the bell crank passes through an aperture formed in a grippingjaw 36, the inner end of which is formed with suitable teeth. This jawextends through the slot 31 and is movable in and out as the bell crankis rocked on its pivot. For this purpose the flanged ring 28 is movablein the direction of the axis of the shaft 23 and has a peripheralchannel 37 in which lies a ring 38. The ring has a lug 39 to which issecured one end of a link 40, the other end of which is secured to ahandle 41 pivoted on a lug 42 formed on the cap 26. The handle 41carries a plate 43 which has a curved under surface 44, this surfacecooperating with a groove 45 which extends on the arc of a circle aroundthe lug 42. Lying in this groove is a ball 46 which is held by a spring47 against the right-hand end of the curved surface 44, as seen in Fig.10. A pair of plates 48, 48, secured to either face of the plate 43,afford a means by which the ball may be introduced in position, and aplunger49 extends through one of these plates and is so positioned thatits rear end may be engaged by a pivotally mounted handle 5() attachedto the handle 41 at 51. plate 43 provide a locking device of a wellknowntype and when the handle 41 is rocked to the right, as shown in Fig. 6,it causes the gripping jaws 36 to move inwardly along radial paths andto engage the nut 52. Vhe-n these jaws have gripped the nut in thedesired manner the handlel 41 is rocked to the left slightly, when theball will be wedged between the surface ot the groove 45 and the curvedsurface 44 on the plate 43. This will serv@ to lock the jaws inoperative position. lVhen the jaws are to be released the handle 50 ismoved slightly, forcing the plunger 49 inwardly so as to force the ballaway from itswedged position. This handle is kkept in such position asto keep the ball free from the wedging surface so long as a freemovement of the handle 41 is desired. Upon release of the handle 50 theball-locking device automatically becomes operative.

The nut 52 is a portion of a coconut cut so as to have an open end, andis preferably half a coconut. This half coconut is held in position bythe gripping jaws 36 and when being inserted in position to be seized bythese jaws, its rounded end bears against a spring-pressed plunger 53which is mounted in a recess formed in the end of The ball, groove andlllll the shaft- 23. Mounted on the end of the 'flange 30 is a screen lhaving an aperture in its `front tace, through which the nut is insertedinto the chuck. This screen encloses `the various parts ci the chuelnasillustrated.

Movable past the table l2 a carriage which has suitable wheels 5i'running on rails 58 on the bed plate ll. Un this ci rriage is supportedthe device by which the nuts are inserted in the chuck and also the toolby which the meat is extracted trom the nuts, and the mechanism whichdrives the tool, 'l`he` device by which the nuts are vinserted in placein the chucla: `consists oi a plate 59, movable in suitable guideways(il), 60, njiounted on the upper bed (il ot the carriage. On this plate59 is an upright plate 62, and extending through the plate 52, near theupper `corners thereoi", `are pins 33. E3;- tending downwardly acrossthe front tace of the plate are arms 6l the lower .ends of which areguided by `means ot a rail secured at either edge ot they plate G9.. @nthe rear face oit the plate there are secured to the pins shorter arms(5G, between. which is mounted a springt?, tending to draw the armstogether. Also on the rear face ol the plate62 is a handle 68 by whichthe device may be moved to and `trom the chuck. On the front face ot theplate 52 is an index 69, by which the `position in which the uut is tobe placed is approximately indicated to the operator. lWhen the halt nutis to be inserted in the chuck .it is placed with its open end lyingagainst thc vface ol the plate G2 by .moving it `downwardly between thearms (il to the appropirate position, thus slneading these arms againstthe spring and causing the nut to be held iirinly between them. Theplate ,62 is then moved up toward the chuck until the rounded end ot the-nut bears against the spring-pressed plunger llllith the nut in thisposition the handle 4l is operated to cause the gripping jaws to gripthe nut and the inserting device may then be moved backwardly away fromthe chuck by the handle 68.

The tool by which the meat is extracted from thenut is indicated at TO,and at its forward end has al plurality of cutting edges 7l so arrangedas to produce shreds of the desired shape and size. The knife that lprefer to use is one similar' to that illustrated in the patent otGeorge D. Olds, Jr., No. 1,438,714, which has a plurality of verticaland transverse cutting edges which produce clean shreds ol the desiredsize. The shank of the tool is secured in a holder 72 by means of [a set`screw 73. The holder is tast on a pin Til, which extends through abearing 75 in a standard 76. At its lower end the pin 74. is encircledby a spring 77 secured at one end to the pin and at theother to thestandard. This spring is so arranged as to ways 79, 79, on the top plateor ie carriage 5G. Mounted in the carriage below these guideways is ascrew lll), supported in suitable brackets. rliis screw carries a gearSl at its outer end which m with the gear 82 on a shaft 83, which is diven by a drm# ing connection, presently to be inscribed., and an arm8lpivotally n'iounted at on the standard 7G., carries a halt nut at itslower end, which is adapted to be held in y engagement with the threadson the screw 80. The screw 8O .is so driven that when the halt nut isheld in Contact therewith the plate 18 and the standard constitutingcarriage 'for the tool holder, will be moved so as to cause. the tool toadvance into the nutshell. rllhe arm 8l is normally blessed so that thehalt nut is out ot engagement 'with the screw threads, by a spring 87secured at one end to the lower end oi the arm 8l and at its other endto a stationary bracket secured to the carriage. At `its upper end. thearm 8l is received in a` guide linger 89, bolted'to the bracket, and thearm 8l carries a plate 90, having a socket 9i `termed on its inner face.il. springdield dog -952 is mounted on the standard 7b in such aposition that when the arm Sel .is swung so that the hall nut engagesthe threads on the screw 8() the dog will lock the n in this position.The rear end ot the dog so positioned that it may be engaged by the rearend 93 oit the tool and the relation ot the parts is such that as thetool enters the. nut

more and more deeply in the operation ot extracting the meat the toolwill be swung` by the curvature ot` the inner wall oit the nut untileventually at a predetermined point in the travel of the tool its rearend will strike the tail of the dog 92 and swing it to the positionlindicated in Fig. '9. This dog then releases the arm 8l and the spring8? on the latter forces it away trom the screw 80 thus interrupting thetravel of the carriage ven 4which the tool and its holder are mounted.

This arrangement, therefore, provides ade vice by which the extractingoperation may be carried on automatically. l'llhen the portion of thecoconut is in place within the chuck the arm 8l is swung so that adriving connection is established between the screw 80 and the carriage`on which the tool and its holder are mounted. As the coconut is rotatedby the chuck the tool is advanced farther and tart-her into the openend, thus extracting the meat in the form of line shreds. As the toolfollows the curvature of the` inner wall of the nut with which it isheld in yielding engagement by the spring 77, the tool is swung about avertical axis and by properly designing the parts the. tool'will beswung sufficiently to move the dog 92 to release the arm 84 when thebottoni of the nut has been reached. The curvature of the nut,therefore, is taken advantage of in interrupting` the travel of thetool, and by this mechanism the extracting voperation is carried onwithout attention on the part of the operator, and is automaticallyinterrupted when the contents of the nutshell has been removed.

The mechanism for driving the screw cor-ists of the shaft 19 previouslymen- Vio-ned. 'lf his shaft extends through va bearing which is mountedon a disc 95, pivotally supported in suitable bearings 96 on a crossmember or carriage 56. Encircling this shaft is the hub 97 of a bevelgear 98 whicli'is splined to the shaft and movable along it while beingcontinuously driven thereby. Mounted in a suitable L-shaped bracket 99,depending from the upper bed plate of the carriage 56, is a shortvertical shaft 100 which carries a bevel gear 101 at its lower endmeshing with the bevel gear 98. rihe vertical shaft 100 lies in the axisof rotation of the plate 95 so that the main carriage 56 may be movedalong its tracks 58 without interfering with the driving connectionbetween the shaft 100 and the shaft 19. As the carriage nioves from theposition shown in Fig. Q to that shown in Fig. 3, the bearing 94 movesabout the arc of a circle by the rotation of the plate 95. The shaft 19swings about the verticalshaft 14 to the center and the gear 98 rollsaround the gear 100. 'ihus the shaft 100 is continuously driven from themain drive shaft 14, regardless of the position of the carriage. At itsupper end the shaft 100 carries a bevel gear 109., meshing with asimilar gear 103 on the shaft 823, and with this arrangement the screw80 is continuously driven from the main drive shaft 14 of the machine,regardless of the position of the carriage 56, but the secondarycarriage on which the tool and its holder are mounted is only drivenfromy the screw 80 when the arm 84 is swung to establish a drivingconnection with the screw 80.

Mounted on the outer end of the shaft 88l is a pulley 104 over whichruns a belt 105, driif'ing a pulley 106 on the shaft 107. This shaftextends across the carriage and carries a pulley 108 over which runs awide belt 109. From the pulley 108 the belt ytravels around an idlerpulley 110 placed The belt 109 provides a conveyor by which the shreddedmeat extracted from the coconut may be discharged from the machine, andas this meat drops from the shell and falls on the belt 1.09, it isconveyed toward the pulley 108 beneath which may be placed a receptacleinto which it is discharged. The idler pulley 110 placed to the rear ofthe pulley 108, permits the meat to be discharged vertically over theface of the pulley into the receptacle.

1n operating the machine a half coconut, produced by suitable cuttingdevices, is placed with its open end against the face of the plate 62 ofthe inserting mechanism. The carriage 56 has meantime been placed sothat this inserting mechanism is in registry with the chuck. rTheinserting device, with the coconut held against its face by thespring-held arm 64, is then moved toward the chuck until the curved endof the coconut bears against the spring-held plunger within the chuck.The coconut is thus properly inserted and centered within the chuck andthe handle 41 is next operated to cause the gripping jaws to seize thenut. When this operation is completed the inserting device is moved tothe rear and the carriage moved along its rails to bring the secondarycarriage on which the tool and tool holder are placed, into registrywith the open end of the nut. The secondary carriage is moved so thatthe tool is in proper relation with the nut and the arm 84 is swung byits handle to cause the half nut on its lower end to engage with thedriven screw 80. The power is now thrown on and the chuck rotates thenut relative to the tool, causing the latter to carry'on its shreddingand cutting operation. At the same time, the carriage on which the tooland holder are mounted, is continuously advanced toward the open end ofthe nut so that the tool enters farther and farther into the nut as theshredding operation continues. During this movement the tool swingsabout a vertical axis as it follows the curvature of the inner wall ofthe nut, until eventually, when it is swung to the desired extent itsrear end strikes the dog 92 and swings it so as to release the arm 84.The latter is then swung by its spring so as to be disengaged from thescrew 80, whereupon no further advance of the cai'- riage takes place.lVhen this point is reached the stopping of the carriage indicates tothe operator that a new nut must be placed in position. He then stopsthe machine, moves the tool carriage to the rear, releases the old nutfrom the chuck and inserts a new one in position by the devices providedfor the purpose. While the shredding operation isbeing carried on thenut meat extracted is deposited on the conveyor belt and delivered atone side of the machine into suitable receptacles. The shredded meat isremovee Atron/i time to time and put up in packages in the usual way.
